Fair360 index data show that organizations with stronger ERG participation also demonstrate greater promotion symmetry — meaning advancement patterns are more consistent across employee groups. In Benchmark Top 10 ERG organizations, promotion gaps are materially lower than in companies with weak or no ERG infrastructure. These findings reinforce an important point: when ERGs are well-supported and integrated into the broader talent system, they function as infrastructure — not informal networks — and are associated with more stable and equitable talent flows.
